In the intermittent exposure test, daphnids were exposed to daily pulses of BO with 24-h mean concentrations equal to those in the continuous exposure test, and the peak concentrations were three times the 24-h mean values. After 28 d of continuous exposure to BO, survival of daphnids was reduced at 80 \u03bcg/L, whereas mean number of young per adult, intrinsic rate of natural increase, and mean weight of adults were all reduced at \u2a7e40 \u03bcg/L. Intermittent exposures to daily pulses of BO for 28 d caused reduced survival of daphnids at 24-h mean concentrations \u2a7e40 \u03bcg/L and reduced mean number of young per adult, intrinsic rate of natural increase, and mean weight of adults at 24-h mean concentrations \u2a7e20 \u03bcg/L. The estimated geometric mean-maximum acceptable toxicant concentrations of BO based on 24-h mean nominal values were 28 \u03bcg/L for continuous exposures and 14 \u03bcg/L for intermittent exposures. These results demonstrated that continuous-exposure studies may not be adequate in assessing herbicide toxicity to aquatic biota when concentrations fluctuate temporally.", "description": "8 p.", "publisher": { "@type": "Organization", "name": "Springer" }, "author": [ { "@type": "Person", "name": "Buhl, Kevin J. kevin_buhl@usgs.gov", "givenName": "Kevin J.", "familyName": "Buhl", "email": "kevin_buhl@usgs.gov", "identifier": { "@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0002-9963-2352", "url": "https://orcid.org/0000-0002-9963-2352" }, "affiliation": [ { "@type": "Organization", "name": "Columbia Environmental Research Center", "url": "https://www.usgs.gov/centers/columbia-environmental-research-center" } ] }, { "@type": "Person", "name": "Hamilton, Steven J.", "givenName": "Steven J.", "familyName": "Hamilton" }, { "@type": "Person", "name": "Schmulbach, James C.", "givenName": "James C.", "familyName": "Schmulbach" } ], "funder": [ { "@type": "Organization", "name": "Columbia Environmental Research Center", "url": "https://www.usgs.gov/centers/columbia-environmental-research-center" } ] }
